PENCIL-TIP.

SPECIFICATION forming part of Letters Patent No. 452,499, dated May 19,1891.

Application filed June '7, 1890- Serial No. 354,551. (No model.)

To all whom it may concern:

Be it known that 1, OSCAR MUssINAN, J r., acitizen of the United States,residing at the city, county, and State of New York, have invented a newand useful Improvementin Pencil-Tips; andthe following is declared to bea full, clear, and exact'description thereof.

Tubular ends or tips for pencils have heretofore been made of a cylinderof paper glued to the pencil and. having an erasive rubber gluedin theouterend; but thiswas a fixture and not removable or reversible.Reversible tips having an erasive rubber held in one end have-heretoforebeen made of a'slotted metal cylinder; but the same are too expensivefor universal adoption and use in conn ection. with a cheap grade ofpencils.

The object of my invention is to make a reversible pencil-tip with anerasive rubber at one end which shall be very cheaply made and can besold with a pencil at a nominal figure; and in carrying out my inventionI make use of a paper cylinder that is sufficiently stiif to maintainits shape, and that is of a size to fit snugly over a pencil, and withinand near one end of said paper cylinder I securely fasten a disk or wadof paper or similar material to form a cup, into which an erasive rubberis put and secured by glue or otherwise. This disk or Wad of paper actsto prevent the force applied to the rubber while in use driving the samefarther into the cylinder, and it also acts as a stop to the point ofthe pencil when the tip is used as a pointprotector.

In the drawings, Figure 1 is an elevation of a pencil and a longitudinalsect-ion of my improved tip upon-the end thereof. Fig. 2 isa similarview, but showing the tip as reversed for use as a point-protector, andFig. 3 is a longitudinalsection of the tip in enlarged size.

A represents thelead-pencil, and B the tip.

My improved reversible tip is composed of a cylinder or tube a, of paperor similar inexpensive material, rolled up to the desired thickness andsize, with the convolutions glued together. A washeror disk I), of oneor more layers of heavy softpaper or similar material, is secured aroundits periphery to the inner surface of the cylinder a, near one end, bygluing the same to place, and a cylindrical block of rubber c is gluedinto the end of the cylinder into the cup-shaped cavity therein, that isseparated from the other part of the tube by the disk or washer b. ,Ifthe rubber 0 were glued in the end of the cylinder and no washer wereemployed, the rubber would be loosened and forced into the cylinder a bythe force applied to it when in use; but by the employment of the washeror disk I), which is secured at its periphery firmly to the interior ofthe cylinder, a strength is imparted to the parts which renders itimpossible to dislodge the rubber end.

In the position shown in Fig. 1 both leadpencil and rubber are ready foruse, and in the position shown in Fig. 2 the point of the pencil isprotected by the reversal of the tip, in which position'the pencil-canbe carriedin the pocket.

I claim as my invention- The combined pencil-tip and removablepoint-protector formed of a-paper tube having a plug of rubber gluedinto one end, and a disk of paper secured at the base of the rubber,substantially as specified.

Signed by me this 3d day of June, A. D. 1890.
